| Summary: | 碩士 === 國立清華大學 === 動力機械工程學系 === 103 === This study investigates analysis, design and control of sensorless switched reluctance motor (SRM). A FEM software (Maxwell 2D) is used to construct an accurate electromagnetic model to obtain the actual inductance characteristics of the SRM. By incorporating the inductance characteristics into a lumped parameter model of the SRM, we can obtain information on estimating the rotor angle for sensorless control purposes. We also propose an input state linearization scheme to deal with the nonlinear voltage-torque relation in the SRM. Finally, we build the driver circuit on the real SRM machine and use Microchip dsPIC30F4011 to implement the controller. Analytical method proposed in this study is applied to a sensorless SRM to achieve the purpose of increasing performance.
